FERTILIZER, ION EXCHANGER AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a fertilizer that is characterized by at least one biodegradable and/or soil-compatible parent substance that carries groups that are capable of exchanging or scavenging ions, and/or structures to which ions are attached that indirectly or directly promote plant growth. The inventive fertilizer is produced by introducing at least one biodegradable and/or soil-compatible substance capable of ion absorption into a ion-containing fluid, absorbing at least one ion type that indirectly or directly promotes plant growth from the fluid into or onto the biodegradable and/or soil-compatible substance and obtaining the substance charged with the at least one ion type from the fluid.
